These high-precision devices are ideal for low-distortion audio, • Low On-Resistance (7.2-Ohms with 5V supply) video, signal switching and routing. Minimizes Distortion and Error Voltages • On-Resistance Flatness, 3Ohm typ. The PI5A126 is a normally open (NO) switch. The switch is open when IN is LOW. The PI5A127 is a normally closed (NC) switch. • Low Charge Injection Reduces Glitch Errors. Q = 1.6pC typ. • High Speed. t = 7ns typ. Each switch conducts current equally well in either direction ON when on. When off, they block voltages up to V+. • Wide –3dB Bandwidth: 326 MHz • High-Current Channel Capability: >100mA These switches are fully specified with +5V and +3.3V supplies. With +5V, they guarantee <10 -ohm ON-resistance. On-resistance • TTL/CMOS Logic Compatible matching between channels is within 2 ohms. On-resistance flat- • Low Power Consumption (5µW typ.) ness is less than 5 ohms over the specified range. These switches • Small MSOP-8 package minimizes board area also guarantee fast switching speeds (t < 20ns). ON These products are available in 8-pin SOIC and MSOP plastic Applications packages for operation over the industrial temperature range o o • Audio, Video Switching and Routing (–40 C to +85 C). • Battery-Powered Communication Systems • Computer Peripherals • Telecommunications • Portable Instrumentation • Mechanical Relay Replacement • Cell Phones • PDAs Functional Diagrams, Pin Configurations and Truth Tables Top View Switches shown for logic “0” input L6 ogicP7 I5A12 PI5A12 1NOF OF 0FON F O PS8328D 08/05/02 1 PI5A126/PI5A127 Dual,Wide Bandwidth Analog Switch 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Thermal Information Absolute Maximum Ratings Continuous Power Dissipation Voltages Referenced to GND V ............................................................................................. –0.5V to +7V + -6 (derate 7mW/ºC above +70ºC) ........................................ 550mW º V , V , V , V (Note 1) ........................... –0.5V to V+ +2V IN COM NC NO Storage Temperature ......................................... –65 C to +150ºC ................................................... or 30mA, whichever occurs first Lead Temperature (soldering, 10s) .................................. +300ºC Current (any terminal except COM,NO,NC) ........................ 30mA Note 1: Current, COM, NO, NC ...................................................... 100mA Signals on NC, NO, COM, or IN exceeding V+ or GND are (Pulsed at 1ms, 10% duty cycle) ........................................ 120mA clamped by internal diodes.
